The Jak and Daxter Trilogy is now Confirmed for PS Vita coming in June.

Sony have confirmed via the blog that, "the trophy set isn’t shared with the PS3 version
so that means there are three more Platinum trophies you can earn for
your PSN ID via this portable collection."
Great news for Trophy hunters.

They went on to say, "The power of the PS Vita allows Jak and Daxter
Trilogy to feature authentically reproduced graphics from the
original games. If you're a longtime fan you'll instantly feel at
home in the game world and new players will get to experience the
world of Jak and Daxter for the first time via the cool new touch
based applications of certain mini games throughout the collection.
Holding these games in the palm of your hand has never been more
exciting and responsive."
